STOVE.

SPECIFICATION forming part of Letters Patent No. 358,470, dated March 1,1887.

Application filed September 8, 1885. Serial No. 176,460. (No model.) Patented in Germany July 1'7, 1883, No. 27,481, and

To aZZ whom it hwy concern.-v

Be it known that I, GUSTAV HEINRICH Miln- TER, doctor of medicine, subject of the King of Prussia, residing at Herford, Westphalia, German Empire, have invented certain new and useful Improvements in Stoves, (for which I have obtained Letters'Pa-tent in Germany, No. 27,481, dated July 17,1883, and No. 34,556, dated August 12, 1885,) and I do hereby de clare the following to be a full, clear, and exact description of the invention, such-as will entains to make and use the same, reference beletters or figures of reference marked thereon, which form a part of this specification.

This invention has relation to that class of stoves known as. magazine-stoves, and has for its object to so construct the stove that the combustion-chamber may be used as a magaand providing the magazine chamber with a solid bottom.

The invention has for its further object to divide a magazine-stove into two compartments for use as a combustion chamber and magazine, and combining therewith means for controlling the amount of fuel fed from the viding the said magazine with a solid bottom. In magazine-stoves of usual construction the grate, said chamber being thus exposed to the action of the fire, and when a strong draft is maintained the temperature, which is accordingly increased, is such as to act detrimentally on the magazine-chamber, destroying its utility in a short time or else causing it to fall or settle on the grate. This and other defects and inconveniences attendant upon the use of the magazine-stoves of usualconstruction are entirely obviated by the stove which I have devised.

My invention consists in the features of construction and combination of parts constituting the stove, whereby the objects of the invention hereinbefore recited are attained, substantially as hereinafter fully described, and as set forth in the claims.

In order to enable those skilled in the art to August 12, 1885, No. 34,556.

Figure 1 is a vertical section of the stove.

' Fig. 2 is a top plan view; Fig. 3, a horizontal section on line a: ac of Fig. 1; Fig. 4, a like section on line y y,- Fig. 5, a detail view of the pawl and ratchet; Fig. 6, a perspective view; Fig. 7, a vertical section of aslightly modified form of stove. Fig. 8 is atop plan View; Fig. 9, a horizontal section on line 00 00 of Fig. 7; Fig. 10, a like section on line 3 y; Fig. 11, a perspective View.

I have shown the stove-as being rectangular in form and of a height considerably greater than the width or depth thereof; butit will be understood that I do not wish to limit myself to the form of the stove, as it is obvious that this may be greatly modified, and said stove may be made more artistic than I have shown the same.

In practice I prefer to construct the stove of three separate sections, a b 0, adapted to rest one upon another, the sections being held securely by means of interlocking flanges or other suitable means, and whereby said sections may be detached from one another when necessary for any purpose.

The section a in Fig. 1 is provided with an interior flange for the support of the grate, hereinafter described, and is also provided with a suitable door or doors, D, for starting and inspecting the fire, and with a door, E, communicating with the ash-pit for removing the ashes, said door being provided with suitable I draftregulating devices or slides.

The lower section, a, above the grate, is lined with fire-brick or other similar material, as shown in Figs. land 7, as a portion of this section is necessarily exposed to the greatest heat.

The interior of the middle section, 1), Figs. 1 and 7, that rests upon the grate-section a, is divided vertically into two chambers, A and 13, either of which may be used as the magazine-chamber, as hereinafter described.

The division of section b may be effected by a central vertical partition or, preferably, as shown, by a double-walled partition, d, formed integral with section b and of such length as I00 to leave an open space below it, as more plainly shown in Figs. 1 and 7, the hollow partition also forming an opening, B, that extends clear across the stove, as more plainly shown in Figs. 1, 3, 6, 7, and 11,whicl1 opening is closed at bottom by a foot-piece, 0', formed on the lateral walls d of section b.

The upper end of the transverse opening B is closed by a head-piece, 0'', cast with or secured to the vertical web or partition-wall C, that divides the upper section, 0, into two compartments, 0 0

The section a is closed at top by a horizontal wall, 0, in which are formed holes K and L, on opposite sides of the partition-wall O, and a short pipe or collar, H, for connecting the stove-pipe thereto.

As shown, the compartment 0 is wider than the compartment 0, and in the top wall thereof is the opening K and short pipe H, said opening K, as well as the opening L, being normally closed by lids or covers.

In Figs. 1 and 4 I have shown the grate-section a as provided with two bearing-flanges, a on opposite sides for the support of the grate, which consists of a single plate, 1), of a size equal to the interior area of the stove, onehalf of which plate has the form of a grate, 1.

As shown in Figs. 1 and 7, the section a has supporting-flanges, upon which the grate-plate p r rests loosely, for purposes presently explained, and from which it is supported in a perfectly horizontal plane. The space below said grate-plate constitutes the ash-pit. In these figures D represents the door through which the tire may be started and inspected, and E the door through which the ashes may i be removed from the ash-pit M, said door being provided with the draft-regulating devices. These latter consist of a screw-rod, e, screwing into the door E, and provided with a plate, 6, which, when the rod is screwed up, closes the openings 0 in the door and effectually prevents any air passing therethrough. Vhen the rod is screwed out the plate 0 necessarily uncovers the openings and allows air to pass in through the same to the combustible. It will be seen that by the above means the draft to the fire may be easily and accurately governed.

In order to regulate the feeding of the combustible material to the fire, and in this manner obtain a greater or less heat, as desired, I provide a regulating slide or gate, .9, Figs. 1 and 7, which is adapted to slide up and down in suitable guide-brackets, s, secured to or formed on the partition (I. This slide or gate 8 extends entirely across the opening or space below the partition d, so as to entirely close said opening and complete the partition from the top section, 0, down to the grate-section a, thus adapting the communicating passage between the chambers A and B to be entirely cut off. This slide or gate may be operated in any suitable manner.

In the drawings I have shown the gate 8 as being provided with a rack-bar, 0, projecting centrally from its upper edge, with the teeth of which rack-bar engages a pinion, amounted on a shaft or arbor, m, which extends through one of the chambers A or B, (in the drawings I have shown it as passing through chamber A,) and said shaft has its hearings in the easing or section b and partition d thereof. The shaft projects from the casing and carries a ratchet-whecl, 7;, with which engages a pawl, Z, to lock the shaft against rotation. For operating the shaft a crank is secured to the end i of the same, which end may be squared, as shown, for the reception of said crank. The stove represented in Figs. 7 to 11 differs but slightly from the stove shown in Figs. 1 to 6, and I will now point out these slight differences.

In Figs. 1 to 6 the section a is shown as pro vided with asingle door, D, through which the fire may be started and inspected, and a door, E, to the ash-pit M, through which door the ashes are removed, said door being provided with draft-regulating devices 0 c e.

In the construction of the stove illustrated in Figs. 7 to 11 I have shown two doors, V \V, applied to the section b, for the purposes of starting and inspecting the fire, and with two doors, D E, applied to the section a, for the purpose of removing the ashes, as shown in Fig. 11.

In Figs. 1 to U the removable grate is formed in one piece, and has one portion solid and the other open. In Figs. 7 to 11 I have shown the section a as having the supportingfianges a and a eross-bar,f, for supporting a gratesection, r, and a solid plate, 12, said grate and plate being loosely supported from flanges a and barf, so that the position thereof may be transposed on their supports, for purposes presently explained.

In Figs. 7 to 11 I have also shown the doors V W and D E in the side wall of the stove instead of the end wall.

The top section, 0, of the stove is, like the ICC grate-plate 'r p, or the grater and plate 1), re-

versible, so that the short pipe or fine H may be made to communicate with either the chamber A or the chamber B, according as the one or the other is employed as the combustionchamber.

As shown in Figs. 1 and 7, the chamber A is used as the combustion-chamber and the chamber B as the fuel chamber or magazine. If it is desired to reverse this arrangement, the top section, 0, of the stove is reversed, so that K II will communicate with chamber 13; then the position of the grate-plate p r, or the grate 1a" and plate 1), is reversed, so that the grate will lie below chamber B. It will be seen that by means of this arrangement the fuel in the magazine is never subjected to a direct draft, the bottom thereof being closed,

and said bottom lying on the same horizontal plane as the grate, the consumption of the fuel in the magazine is effectually prevented.

The operation of the stove may be briefly described as follows: The fire being started,

the combustible is introduced through the opening L to any desired extent. The chamber A in this instance serves as the combustion-chamber. The opening K is provided with a lid, or a cooking-vessel may be placed in the hole instead of the lid. The products of combustiomas will be seen, rise and pass through the flue H, which is connected with the stove-pipe or other draft-flue. If, however, it is intended to use the chamber A for the magazine-chamber, the top section, 0, of the stove is reversed, as above described. The grate is then also reversedthat is to say, the solid portion p is brought beneath the chamber A-the chamber B in this instance serving as the combustion-chamber. To regulate the feed of the combustible to the grate, the slide sis either raised or lowered by the means hereinbefore described, and in a manner thatwill be readily understood.

I. would have it understood that I do not limit myself to the exact construction of stoves hereinbefore described, and as shown in the drawings, as these may be varied to'a great extent without departing from the spirit of fuel fed from one chamber to the other, and a horizontal plate, half of which is formed as a grate, substantially as and for the purpose specified.

3. A magazine-stove divided by a transverse vertical partition into a combustion and fuel chamber communicating at their lower ends, in combination with a vertically-movable slide or gate for regulating the amount of fuel fed from one chamber to the other, and a reversible grate, substantially as and for the purpose specified.

4.. A magazine-stove consisting of a lower grate-section, an intermediate section divided vertically into two chambers or compartments communicating with each other by an opening or passage at their lower end above the grate, a regulating slide or gate for said opening or passage, and a reversible top for said stove, divided also into two compartments, one of which compartments is provided with a draftiiue, whereby either of the chambers of the stove may be used as a magazine-chamber, as described.

5. A magazine-stove divided into two chambers or compartments communicating with each other by a passage at their lower end above the grate, in combination with a reversible grate extending across both compartments and having one-half thereof formed solid, and a reversible top for said stove divided into two compartments, one of which is provided with a draft-flue, substantially as described, for the purpose specified.

6. A magazine-stove divided into two chambers or compartments communicating with each other at their lower ends, a horizontal grate-plate having one half formed solid and the other provided with grate-bars, whereby a solid bottom is provided for one of said compartments, and a regulating slide or gate for controlling the amount of fuel delivered from one compartment to the other, substantially as described, for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.
